Controlling the broadband enhanced light chirality with L-shaped dielectric metamaterials
Ufuk Kilic, Matthew Hilfiker, Shawn Wimer +4
The inherently weak chiroptical responses of natural materials limit their usage for controlling and enhancing chiral light-matter interactions. Recently, several nanostructures wi…
Nanocolumnar Material Platforms:Universal structural parameters revealed from optical anisotropy
Ufuk Kilic, Yousra Traouli, Matthew Hilfiker +6
Nanostructures represent a frontier where meticulous attention to the control and assessment of structural dimensions becomes a linchpin for their seamless integration into diverse…
Quantum Composites with the Functionality Defined by the Charge-Density-Wave Phase Transitions
Zahra Barani, Tekwam Geremew, Megan Stokey +7
We demonstrate a unique class of advanced materials - quantum composites based on polymers with fillers comprised of a van der Waals quantum material that reveals multiple charge-d…
Strain and composition dependencies of the near bandgap optical transitions in monoclinic (AlGa)O alloys with coherent biaxial in-plane strain on (010) GaO
Rafał Korlacki, Matthew Hilfiker, Jenna Knudtson +7
The bowing of the energy of the three lowest band-to-band transitions in -(AlGa)O alloys was resolved using a combined density functional theory (DFT) and…
Infrared dielectric functions and Brillouin zone center phonons of -GaO compared to -AlO
Megan Stokey, Rafal Korlacki, Matthew Hilfiker +11
We determine the anisotropic dielectric functions of rhombohedral -GaO by far-infrared and infrared generalized spectroscopic ellipsometry and derive all transverse opti…
Optical phonon modes, static and high frequency dielectric constants, and effective electron mass parameter in cubic InO
Megan Stokey, Rafal Korlacki, Sean Knight +8
A complete set of all optical phonon modes predicted by symmetry for bixbyite structure indium oxide is reported here from a combination of far-infrared and infrared spectroscopic…
Broadband enhanced chirality with tunable response in hybrid plasmonic helical metamaterials
Ufuk Kilic, Matthew Hilfiker, Alexander Ruder +4
Designing broadband enhanced chirality is of strong interest to the emerging fields of chiral chemistry and sensing, or to control the spin orbital momentum of photons in recently…
Anisotropic dielectric functions, band-to-band transitions, and critical points in α-Ga2O3
Matthew Hilfiker, Rafał Korlacki, Riena Jinno +6
We use a combined generalized spectroscopic ellipsometry and density functional theory approach to determine and analyze the anisotropic dielectric functions of an -GaO…
Tunable plasmonic resonances in highly porous nano-bamboo Si-Au superlattice-type thin films
Ufuk Kilic, Alyssa Mock, Rene Feder +6
We report on fabrication of spatially-coherent columnar plasmonic nanostructure superlattice-type thin films with high porosity and strong optical anisotropy using glancing angle d…
